sic - simple irc client
|
||||||
|
=======================
|
||||||
|
sic is an extremly fast, small and simple irc client. It reads commands from
|
||||||
|
standard input and prints all server output to standard output. It multiplexes
|
||||||
|
also all channel traffic into one output, that you don't have to switch
|
||||||
|
different channel buffers, that's actually a feature.
|
||||||
|
|
||||||
|
|
||||||
|
Installation
|
||||||
|
------------
|
||||||
|
Edit config.mk to match your local setup. sic is installed into
|
||||||
|
/usr/local by default.
|
||||||
|
|
||||||
|
Afterwards enter the following command to build and install sic
|
||||||
|
(if necessary as root):
|
||||||
|
|
||||||
|
$ make clean install
|
||||||
|
|
||||||
|
|
||||||
|
Running sic
|
||||||
|
-----------
|
||||||
|
Simply invoke the 'sic' command with the required arguments.
